Help - Narrow wide chainring on old road bike

[figbat]

What about this one?

It's very nice that one, but it's 36T only
And my BB has a Square Taper JIS

After checking all the options on the market, and also the shipping and duty costs and Covid time Constraints (I live in Portugal) I ordered these components:

JIS/Square taper, BCD 110
FSA Vero spider crankset 170mm arm and Rafe Face 40T Narrow wide chainring

Think you may need 5 short chainring bolts too. Isn't that crankset designed to run double rings?

as opposed to normal ones:

Maybe: https://www.chainreactioncycles.com/race-face-outer-ring-bolt-set/rp-prod15231
But check, and check there are really 5 in the pack!

I ordered these screws:

I think they're the same as your second link.

If they're too long I will buy other ones locally, will wait for the stuff to get here and check it out

thank you

Installed the crankset and the NW chainring,
the bolts I bought were a bit longer like Ajax Bay said , I should have bought Short bolts but I didnt know at the time I ordered.
I'm using some washers for now.

I went for a 3 hours ride yesterday and the bike runs really smooth it's great. The Chain didnt jump at all, it's really stable.
Normally in a ride like this the chain would jump from the front chainring 20 times.

I was also impressed by how smooth and noiseless the Race Face NW chainring is. It's a delight to ride the bike now.
